JOHN MIDDLETON, OF NEW YORK, N. Y.

ICE-CRUSI-IER.

Specification of Letters'latent No. 31,027, dated January 1, 1861A.

To all whom it may concern.'

Be it known that I, JOHN MIDDLETON, ot the city, county, and State of New York, have invented a certain new and useful IceL Crusher; and I do hereby declare the followling to be a full and exact description 'of the same, reference being had to the accompanying drawings.

My invention is a novel and simple apparatus for crushing and discharging small quantities of ice for cooling drinks, etc.

To enable others skilled in the art to make and use my invention I will proceed todescribe the construction and operation of the saine, by means of the dra-wings in which,

Figure l is a longitudinal section and Fig. 2 is a cross section on the line S, S, in Fig. l.'

Similar letters of reference indicate like parts in both figures.

, A is a receiver made of metal and supported upon legs a, a, one at each corner. On one side of this receiver is fixed a toothed jaw B as represented. On the opposite side is a square case or chamber C litted to receive a sliding jaw D and permit it to slide to and from B in proper ways, which keep it in position. This jaw D has also sharp teeth upon its face which are adapted to t intermediately in the teeth on B. The jaw D receives its .motion from a lever E mounted in proper bearings on the chamber C, the end of the lever E which is connected to D heilig slotted as represented, to permit it to move in the a rc of a circle while D moves in a right line. A spring F is attached to D and t-he end of chamber' C, to bring back the jaw D and lever E, when thehhand is removed from the latter, but this may be dispensed with if desired, the hand being made to replace the lever E after crushing the ice. The bottom, G, of the recever A is tted to slide in proper grooves in A and C, as is shown more plainly in li`ig. 2. To this sliding bottom a spring H is attached with the end bent downward and carrying on its upper surface several prohold the sliding bottom G always in the position shown in Fig. 1.

K is a projecting pin. attached to l), and so arranged that when D is pressed forward it is caught by one of the projections la, and in its return motion causes (ur to be removed from the position shown, opening the receiver A so that the crushed ice may fall out through a spout or funnel L into a glass M or other vessel placed underneath to receive it.. As the jaw, D, recedes, carrying with it the slide G, the end ot' H strikes a projection N on the case C which releases the former from the pin K and allows the spring I to close G again, ready to support a fresh charge of ice.

In operating my machine, a glass, M, or other suitable vessel, is placed in the position shown and a lump of ice, represented by the blue outlines, is dropped in the receiver A. The hand is then placed upon lever E which is pressed downward forcing inward the liaw D causing the sharp teeth on both D and B to penetrate the ice and break it into very small fragments. E and D are then restored to their rst position, either by the tension of the spring (I or by a reverse motion ot' the hand, and the early portion o1u this motion, by the action of K upon /1, withdraws the bottom (lr and allows the crushed ice to t'all into' M. The continuance of this motion brings l-l into contact with N and depresses it somuch as to detach l. from K after which (lr is immedi- .ately replaced by thespring l and the ma together substantially in the manner and' for the purpose herein set forth.

In testimony whereof I` have hereunto set my hand m the .presence oi two subscribing witnesses.
